“Perks” of Maintaining Your Air Conditioner

Maintaining your air conditioner is not a good idea, it’s a excellent idea. 

Isn’t is just the most thrilling thing when it’s 100 degrees outside and your Air Conditioner decides to call in sick that day? Leaving you to handle whatever issue is going on and having to call in your local HVAC Contractor. Take a look at the young man below, it’s summer time and he needs not be worried about being cool in the summer. But, for some reason, he is….


How about when it’s winter time. Do you want to be cold & shivering under twenty blankets? Or would you rather be cuddled up on the couch, drinking some hot chocolate, and enjoying family time? Seems like an easy answer, Right? The gentleman in the green jimmies below, is clearly having some HVAC issues and not able to enjoy anything mentioned.


Other than being cool in the summer and warm in the winter, there are a MANY MORE PERKS to maintaining your HVAC system.

Over a years time, dirt builds up on the coil. While the filter helps to slow down the soiling process, the dirt will still find it’s way to your coils. Dirt on coils decreases your airflow, and insulates the coil. As far as the outside coils, they too, become very dirty. Mowing the grass, leaves falling from trees, and wind blowing dust….these all contribute to the dirt build up on the coils.

When regular PM’s are done, you will achieve the following:

  • Preventing costly breakdowns
  • Reducing energy costs
  • Extending the life of the equipment
  • Improving system performance
  • Making the system safer

One of the ways to accomplish these goals are to clean and coat your HVAC system with products that will not eat away at your coils, nor inhibit heat transfer.

Say hello to a Coil Cleaning Kit. It has everything you need to solve any build up problems on your coils. Better yet, it will last a full year. It comes with our Instant Powder Kegs coil cleaner and First Strike Micro Coat easy to use annual coating.

Instant Powder Kegs is a powdered coil cleaner, that is easy to use, clean up and transport. Just mix with water, spray on and rinse.The coil cleaner is removing the dirt and build up on the coils. Then, apply the First Strike Micro Coat which is an annual coating that will repel anything from sticking to your coil. Leaving you with a years worth of protection on your coil.

Technical Corner: Tips for Cleaning Dirty Air Conditioner Coils

It is difficult to clean HVAC coils effectively due in part to coil design.  For multiple row coils, the copper tubing is staggered, and this prevents a stream of water from entering into the coils too deeply.  Usually the water velocity penetrates only the first few inches of a coil to loosen deposits.

Fouled coils lead to increased pressure drop across the coils. When pressure drop increases, more fan horsepower is required. This in turn draws more power, resulting in greater current consumption.

Pressure drop measurements across the coil when it is new are a valuable base line for performance.  Differential pressure that increases by more than one and a half to two times for sure indicates problems with coil cleanliness.

Cleaning coils also plays an important part in air quality.

Here are some rules to follow in cleaning coils:

1)Hot water always works better than cold water when it comes to cleaning.

2)Foaming cleaners, such as our product Instant Powder Keg, are generally better than non-foaming cleaners to remove biofilm and other deposits.

3)Certain areas of the coil may have more deposition than other areas.  A gentle flush of water through the coil may identify areas that are particularly fouled.

4)Cleaning from the bottom of the coil to the top is recommended. Multiple cleanings of the coil may be necessary due to heavy deposition.

5)After completion of cleaning, again run the hose through the coil to see if water now flows freely through areas previously found to be restricted.

6)Coil cleaners may be either acid, neutral, or alkaline in nature.  Many manufacturers call neutral pH or alkaline pH cleaners “non-acid” cleaners. Both acid and alkaline cleaners will attack coil fins, causing pitting and other corrosion. To reduce this problem, coils must be copiously rinsed with water to neutralize any chemical residual left on them.

7)Sanitize the coils using an iodine-based anti-microbial.

8)Apply a molecular coating to the coils, such as our product First Strike Micro Coat, to reduce future build up.

Properly cleaning coils as part of a preventative HVAC maintenance program can save a building owner thousands of dollars.

From the Field: Dirty Sock Syndrome

Okay, it’s that time of year. For much of the U.S., the heating season began about a month and a half ago. Here in North Carolina, and more specifically my household, the heating season has only been around for about three weeks. Now don’t get me wrong, it’s been cold enough at night to run the heat, but during the day we find ourselves turning the AC back on – a common thing in the Southeast.

When the heat pump goes into defrost mode, or the HVAC unit is switched from heating for a brief time, then back to cooling, a condition known as “Dirty Sock Syndrome” can arise.  DSS is described as a musty, moldy, dirty sock odor coming from HVAC systems when they first start into cooling mode. DSS is caused by bacteria that attaches to, and grows on indoor evaporator coils. When the coils cool down and get damp, the bacteria release their gases all at one time into the air causing the unpleasant odor.

Some people have gone as far as to almost sell their homes because they couldn’t get rid of the smell. BUT HAVE NO FEAR! Here is a way for you to eliminate that smell and maintain a clean, healthy environment through a little preventive maintenance.

  1. Clean the coils at the end of the cooling season with Instant Powder Kegs. Cleaning the coils before the heating season will get rid of any contaminants such as dirt, biological buildup and other material.
  2. Sanitize the unit thoroughly. Use EPA-registered Fast Attack, an HVAC system sanitizer specifically designed for HVAC interiors. Iodine based sanitizers are an ideal choice, as iodine’s effectiveness has been well documented. Hospitals have used iodine to sanitize before surgery for the last 150 years for a reason!
  3. Protect the coil from fouling by using Green-Certified First Strike Micro Coat. Transform the coil into a “self-cleaning” coil, one that repels particles and keeps matter from adhering to the surface.
  4. Round off the procedure by adding a timed-release drain pan protectant. This will eliminate clogs and overflows that can occur once the cooling season starts back. Either Green-Certified PanGuard or EPA-Registered Algae Guard will work.

All of these products are safe and easy to use, requiring minimal PPE. By following these simple steps, it will ensure that when you start up your AC at the beginning of the cooling season, you aren’t left saying….“Ewww, THAT SMELL!”
